Abstract- Ribosomal and ubiquitin protein coding sequence data are generated from 20 arthropods and five close relatives. These molecular data are combined with morphological characters derived from the literature to approach arthropod phylogenetics from the perspective of total evidence. Trilobita were included in the analysis through morphological comparison alone. The overall data strongly support arthropod monophyly. Recent molecular analyses which have yield different results are shown to have been based on few characters, few taxa or both. The most parsimonious explanation of the data is (Annelida + (Onychophora + (Trilobita + Chelicerata) + (Crustacea + (Myriapoda + Hexapoda))))). The data are largely concordant both internally among data sets and externally with previous cladistic anatomical analyses.
摘要——核糖体和泛素蛋白编码序列数据来自20种节肢动物和5种近缘物种。这些分子数据与从文献中获取的形态特征相结合，从总证据的角度探讨节肢动物系统发育。三叶虫仅通过形态比较被纳入分析。总体数据有力地支持节肢动物的单系性。结果表明，近期得出不同结果的分子分析是基于很少的特征、很少的分类单元或两者皆少。对数据最简约的解释是（环节动物 + （有爪动物 + （三叶虫 + 螯肢动物） + （甲壳动物 + （多足动物 + 六足动物））））。这些数据在数据集内部以及在外部与先前的分支解剖学分析在很大程度上是一致的。
